MODE OF CONSTRUCTING SHAFT-CLIPS FOR CARRIAGES.

Specification of Letters Patent No. 1,078, dated January 22, 1839.

To all whom it may concern:

Be it known that I, JOHN Coornn, of the city, county, and State of NewYork, formerly of Bristol, England, have invented a new and usefulImprovement in the Construction of that Portion of-the IronworkBelonging to Carriages Called the Shaft- Clips, and that the followingspecification contains a full and accurate description of the same.

My improved shaft-clip with its immediate a'ppendages, consists of thefollowing pieces or parts. First, the shaft-clip A, (see Figure 1,) inthe annexed drawings, which is secured to the under surface of theaxletree B, by means of the axle-clip C, striding over the same andsecured underneath by the nut-s D, D.

E, is the strap to which the shaft is attached, and upon the back end ofwhich (made entire with the same) is the pipe-eye F, which plays in thebox of the shaft-clip upon the bolt G, which is secured by the nut H,upon the end of the same.

As my improvement consists exclusively in the form of the joint of theshaft-clip I will describe it separately. (See Fig. 2.) In the annexeddrawing J, is the shank end of this clip which is attached to theaxletree. The opposite end which forms the joint is widened andfork-shaped, the prongs K, K, of which are flattened and curved upwardforming about three fourths of a circle about 1 inch in diameter withheads L, L, of corresponding dimensions upon the ends forming acylindrical box about 3 inches long open at the back from head to head,and about one inch more or less in front and around the upper sectionbetween the prongs. In this box or case, 0, plays the pipe-eye F, (seeFig. 3,) forming a kind of knuckle joint, the bolt Cr, passing throughthe heads L, L, and the center of the pipeeye, as before mentioned. Bythis arrange ment accidents arising from the failure of the bolts, asordinarily constructed, (see Fig. 4) will. be obviated; as the pipe-eyeF, cannot be removed from the clip-box 0, although the bolt G, iswithdrawn until the clip J, is disengaged from the axle-tree B. Forheavy carriages, the prongs K, K, may be united above, as at the bottom,and be secured in like manner upon the top of the axle-tree or bed, bythe clip C, or (see Fig. 5,) by bolts through the holes P, P, P, P,through the straps R, R.

hat I claim as my invention in the above described implement, and forwhich I solicit Letters Patent, secured to me, and my legalrepresentatives is The exclusive privilege and right of mak ing,construction, &c., of box-joints in shaftclips for carriages, &c., insuch manner that the pipe-eye, or connecting end of the shaftstrap shallnot depend upon the bolt for its support, but on the contrary upon thebox or case in which it is inclosed in the manner herein described,whether the form of the said box be cylindrical, conical, or spherical.
